Macdonald was a very early mining camp opened by the MacDonald Colliery Co., whose owner was Symington MacDonald. Operations began in 1893 and ceased in 1938. By that point the New River Co. was running the MacDonald operation. They kept a company store opened there after the mines closed.
An August Saturday evening in Mount Hope in front of the final Macdonald company store, built in 1941 to replace an earlier one. It is just down
the street from the (former) New River Co. office building, and all the structures behind it were New River Co. warehouses.

The Macdonald camp - still inhabited

The coke ovens at Macdonald, built in the mountainside, are in poor condition because the area above it was strip mined. This also took out the incline.

My theory is that this was the powder house.
